Spectra UL633N Universal Grade Laser

The UL633N Universal Laser provides precise dual-axis alignment without the need for perpendicular positioning of receivers, making it ideal for grading sports fields, parking lots, and driveways. It works with two receivers simultaneously, allowing automatic grade measurement between elevation points in Grade Match mode.

For high-precision jobs like airport runways, the Dual Axis PlaneLok feature locks the laser plane to two receivers, preventing drift from vibrations or temperature changes.

The UL633N also offers a plumb beam that switches to a rotating fan beam, detected by the SpotFinder SF601. This allows easy grade measurement through pipes or trenches in Spot Match mode, and 90-degree layouts on concrete pads or drywall. The SpotLok mode locks the beam to the SpotFinder for accurate alignment, reducing rework.

The included RC603N remote control lets contractors operate the laser from up to 150 metres (490 feet), speeding up setup and adjustments directly from a machine cab.

Features and benefits

• Automatic Electronic Self-Leveling ensures fast, easy setup for horizontal, grade, and vertical plumb measurements.
• Large Compensated Grade Range from -25% to +25% for flexible grading applications.
• Quick Setups with a combined radio/infrared remote control for horizontal, vertical, and grade adjustments.
• Electronic Leveling Vibration Filter reduces the effects of vibrations typically encountered on tall tripods, high winds, or high-vibration job sites.
• No Rework due to automatic temperature, grade, and cross-axis compensation.
• Dual Automatic Axis Alignment provides precise alignment to two desired points without positioning the receivers 90° perpendicular (+/-40° range on both Y- and X-axes).
• Horizontal Angle Measurement allows angle measurement between two points via two-axis alignment on the Y- or X-axis.
• Automatic Spot Align guides the beam accurately to the target point in the horizontal axis, maintaining the Z-axis grade value.
• Spot Search uses the SpotFinder SF601 to manually find the centre of the plumb beam.
• Single and Dual Grade Match (Y- and X-axis separately or simultaneously) and Spot Match (Z-axis) display existing grades over unknown ground, eliminating time-consuming calculations, grade plan searches, and over-excavation.
• Single and Dual PlaneLok (Y- and X-axis separately or simultaneously) and SpotLok (Z-axis) automatically lock onto existing elevation or vertical alignment points, preventing drift or errors due to calibration issues or weather conditions.
• Rugged Design withstands a 1-metre (3-foot) drop onto concrete, reducing service and repair costs.
• Mask Mode reduces interference from other crews on the job site
• Adjustable Rotation Speeds and Scanning Mode offer additional versatility for interior applications.
